Standalone DC microgrids often have challenges in energy management for a long time horizon due to uncertain renewable energy sources and volatile loads. This paper presents a centralized energy management strategy (EMS) for a standalone DC microgrid with solar PV, fuel cells, and a battery energy storage system (BESS).
Integrating hydrogen and battery storage can deliver sustained energy and effectively manage microgrid demand and surplus. Key challenges include integrating power electronics with fuel cell technology for efficient renewable energy conversion. This paper presents a hybrid ESS with 1 kV DC bus voltage.
Abstract: This paper presents a hybrid Energy Storage System (ESS) for DC microgrids, highlighting its potential for supporting future grid functions with high Renewable Energy Sources (RESs) penetration. While hydrogen ESS provides long-term energy stability, it typically has slower response times than batteries.
The energy storage system can sufficiently alleviate the shortage of new energy such as photovoltaic/wind that is greatly affected by the environment. Higher-capacity lithium-ion batteries and higher-power supercapacitors (SCs) are considered ideal energy storage systems for direct current (DC) microgrids, and their energy management is critical.
